it’s a while I don’t use Logic.
My latest version was 2.3.26. I was quite happy with that.
I’m running some Async serial analyzers together with some custom extensions on them.
I’ve downloaded the 2.3.36 version and the responsiveness of Logic got a lot worse.
Sometimes when i press the stop button nothing happens for >10 seconds, sometimes it doesn’t stop at all. I had to kill the process several times.
The acquisition image (while it is acquiring) is stuttering all the time.
Did you change something in the Async serial extensions processing?
Right now I went back to 2.3.26 and it works pretty well.
